TO ALL WHOM IT MAY CONOERN:

Be it known that I, BENJAMIN T. HARRIS, of Brooklyn, in the county of` Kings, and State o'f New York, have invented, made, and applied to use a certain new and useful Improvement in Machines for Inserting Screw` Eyes; and I do hereby declare the following to be a full, clear, and exact .description of the said, invention,

reference being had to the annexed drawing, making part of this specification, wherein-f Figure 1 is a vertical section of my said machine; andi Figure 2 is a plan of the same, with the screw eye shown in red lines, in the position it occupies in `the machine. l f

Similar marks of reference denote the same parts. y

Screw eyes are inserted into the backsand edges of i picture frames, show cards, site., for suspending them. Where there are a large number of these frames much time is consumed in measuring the position of the eyes and inserting the same, either by screwing in the eye with the fingers or rst boring the hole. The operation is very tedious and tiring to the fingers, and frequently, through inattention, the eye is not inserted into therigllt place, and the picture will not hang straight.

I am enabled to insert the screw eyes wit` great rapidity and accuracy, and the personal.:.inconveniencejin `so doing is avoided. v e i e In the drawing, a is the table or bed upon which is laid the frame, and upon which bed :is to4 be placed an adjustable gauge to determine the position of the frame relatively to the machine. b is the metal frame of `the machine, attached to the bed a by the screw c, and the frame b carries at its upper end the shaft d of theV eye- The eye-holder `is made j 7 as a fiattened recess at the end of the shaft d, of a size and shape to receive the eyel portion with, the screw i 4shank thereof on the line of the axis of d, a notch, at being provided for the shank of the screw eye, andran` i overhanging lip at o, to grasp the eye and rotate `the same to screw the shank into theframe as" the handle lz. is` 1 turned. The eye-holder e may be screwed upon the end of d, so as to be changed to suit` diierent sizesiof `eyes.;` `1 The machine may be raised or lowered, so as to bring the screw eye at the proper height from' the table or rest` i holder e. f is a pinion at one end of d, drivenfbya wheel, g, and cra-nk or handle, L. e

forthe frame. y

What Iclaim, and desire to secure by` Letters Patent, is l i The device for inserting screw eyes in picture frames, &c., consisting of the `eye-holder e, formedsuhstanf.`

tially as specified, and rotated, by the mechanism herein described, substantially as set forth.

In witness whereof I have hereunto set my signature, this 25th day`of October, A. 1331866.

The nature of my said invention consists inan eye-holder revolved by mechanism, so that the frame can be` presented and guided by a gauge while t screw eye is rotated by the holder and screwed in. i By thsmeans`-`
